RELATED APPLICATION

The present application claims priority to U.S. Provisional PatentApplication No. 61/604,417, filed on Feb. 28, 2012, which is fullyincorporated herein by reference.

TECHNICAL HELD

The present disclosure relates to methods, systems, andcomputer-readable media for providing physical training. Moreparticularly, the present disclosure relates to methods, systems, andcomputer-readable media for providing instant feedback and objectiveassessment of the effectiveness of the physical training.

BACKGROUND

In sports training, an athlete's training process is normally directedby a coach. The coach typically designs training sessions and monitorsthe athlete's performance. In this traditional framework, the assessmentof an athlete's performance largely depends on the coach's experience,judgment, and patience. It is often difficult for the athlete to receiveinstant feedback from the coach. In addition, the feedback may not bebased on objective measures. In physical therapy especiallyrehabilitation treatment, a physician often assesses a patient'scondition based on overall physical appearance. Subtle imperfections,such as slight imbalance between injured and non-injured legs, aredifficult to capture. Therefore, it is desirable to develop systems andmethods for providing instant feedback and objective assessment of theeffectiveness of physical training.

Controller 300 may be a general purpose computer such as a laptop,a portable computing device such as a tablet or a mobile phone, or acomputing device dedicated for physical training. As shown in FIG. 3,controller 300 may include a processor 310, a memory/storage module 320,a user input device 330, a display device 340, and a communicationinterface 350. Processor 310 can be a central processing unit (“CPU”) ora mobile processor. Depending on the type of hardware being used,processor 310 can include one or more printed circuit boards, and/or amicroprocessor chip. Processor 310 can execute sequences of computerprogram instructions to perform various methods that will be explainedin greater detail below.

Memory/storage module 320 can include, among other things, a randomaccess memory (“RAM”), a read-only memory (“ROM”), and a flash memory.The computer program instructions can be stored, accessed, and read fromthe ROM or flash, or any other suitable memory location, and loaded intothe RAM for execution by processor 310. For example, memory/storagemodule 320 may store an operating system 321, a software application322, and a database 323. Further, memory/storage module 320 may store anentire software application or only a part of a software applicationthat is executable by processor 310.

In some embodiments, software application 322 or portions of it may bestored on a computer readable medium, such as a hard drive, computerdisk, CD-ROM, DVD±R, CD±RW or DVD±RW, HD or Blu-ray DVD, flash drive, SDcard, memory stick, or any other suitable medium, and can be read andacted upon by processor 310 using routines that have been loaded tomemory/storage module 320.

In some embodiments, controller 300 may be connected to anaccessory 360 through communication channel 370. Accessory 360 mayinclude, for example, sensor pad 110 or an external camera (not shown).

FIG. 4A is a schematic diagram of an exemplary sensor pad, in accordancewith some disclosed embodiments. Referring to FIG. 4A, sensor pad 400may include a number of sensor units 410 and an interface 420. Sensorunits 410 may be assigned predetermined identifiers, such as numbers1-5, as illustrated in FIG. 4A. It is noted that different number ofsensor units, different kinds of identifiers, and different manners ofidentifier assignment (e.g., the arrangement and order of theidentifiers) may also be used. Sensor pad 400 may provide signalsindicating whether a particular sensor unit is touched or pressed. Insome embodiment, sensor pad 400 may also provide signals indicating thetime duration of the pressure or force applied to the sensor pad 400.The signals may be sent to controller 120 (FIG. 1) through interface420.

FIG. 4B is a schematic diagram of an exemplary sensor unit, inaccordance with some disclosed embodiments. In FIG. 4B, the sensor unitincludes a top panel 412 and a bottom panel 414. When a user touches orpresses the sensor unit, top panel 412 moves downward toward thedashed-line position. Such position change may lead to a change ofresistance, which may be sensed by sensor 416. Sensor 416 may in turngenerate a signal indicating that the sensor unit has been touched orpressed, based on the resistance change, and output the signal tointerface 420 for communication with controller 120.

FIG. 5 is a flow chart of an exemplary method of determining timeduration of touching a sensor unit, in accordance with some disclosedembodiments. As shown in FIG. 5, method 500 may include a series ofsteps, some of them may be optional. In step 502, sensor 416 readsresistance of a subsequent sensor unit. For example, as shown in FIG.4A, the resistance of sensor units 1-5 may be read sequentially, and anext sensor unit may indicate, for example, sensor unit 5 after thesteps described in FIG. 5 has finished a cycle for sensor unit 4. Instep 504, the position of the sensor unit can be determined based on theresistance. For example, the resistance may be smaller when top panel412 moves DOWN than when top panel 412 moves UP. The UP/DOWN positioninformation can be saved. In step 506, it is determined if the positioninformation has been changed, compared with the previously savedposition information. If the position information has changed, the newposition can be sent to controller 120. In step 508, it is determined ifthe position has changed from UP to DOWN. If so, the new positionindicates that the sensor unit has been touched or pressed, and a timercan be adapted to measure the contact time. In step 510, it isdetermined if the position has changed from DOWN to UP. If so, the newposition indicates that the sensor unit has been released. The timer canbe stopped and the time duration of the pressure or force applied to thesensor unit, for example, can be saved. The process then returns to step502 to read the next sensor unit (e.g., sensor unit 1). Method 500 maybe initiated upon receiving a request from controller 120. Contact timeinformation may be sent to controller 120, once available.

In some embodiments, software application 320 may include a plurality ofpre-set drills for performing physical training. Examples of pre-setdrills may include count drills, react drills, sequence drills, verticaldrills, and agility drills, as described herein. A user may also createa customized drill, a new category of drills, and/or a playlist ofdrills.

Count drills are designed to test and/or improve speed or quickness ofmovements. The user is instructed to perform pre-determined movementsduring count drills. In an exemplary count drill, controller 120 mayactivate one or more sensor units 112 (or all sensor units in someembodiments) on sensor pad 110. Controller 120 may record the totalnumber of touches on the activated sensor units during specific timedurations. Alternatively, controller 120 may record the time durationfor finishing a pre-set number of touches. The goal of the user is totouch the activated sensor units as quickly as possible. When the usertouches a sensor unit, the corresponding visual indicator may light upon display panel 202. The number of touches and/or the time (spendingand/or remaining) can be displayed on display panel 202 in real time.The user may be able to choose or program the pre-determined movements(e.g., type or manner of movements, sensor units to be activated,specific order of touches, etc.), number of touches to be accomplished,and/or time duration of the drill. In another example, the user canstand on the front or back two sensor units (e.g., 1 and 2 or 4 and 5 inFIG. 4A), and controller 120 may activate the two sensor units as a leftand a right touch target. The number of left and right touches can bedisplayed separately on display panel 202 in real time. The time(spending and/or remaining) can also be displayed on display panel 202.Contact time may also be determined by, for example, method 500illustrated in FIG. 5.

React drills are designed to test and/or improve a user's speed ofreaction to visual indicators 204 displayed on display panel 202. In anexemplary react drill, a sequence of visual indicators 204 can beprogrammed to be displayed on display panel 202, and a user needs toreact to the visual indicators 204 and perform a series of movements,e.g., by touching the corresponding sensor units 112 on sensor pad 110.In some embodiments, the visual indicators can be assigned a certaincolor, and the user is instructed to react to the visual indicators withthe assigned color. In some embodiments, the visual indicators can beassigned different colors, and the user is instructed to react tocertain colors, but not others. The user reacts to the visual indicatorby touching the corresponding sensor unit as quickly as possible. If theuser correctly touches the corresponding sensor unit, controller 120 mayreceive a signal from sensor pad 110 indicating a corresponding sensorunit has been touched. Controller 120 may then determine that the userhas completed the expected movement and record a correct touch. If theuser touches an incorrect sensor unit that does not correspond to the“react to” visual indicator, or the user touches a sensor unitcorresponding to a “don't react to” visual indicator, or the user failsto touch the corresponding sensor unit fast enough (e.g., thereaction/response time is longer than a predetermined threshold),controller 120 may determine that the user does not complete theexpected movement and record an incorrect touch. The total number ofcorrect touches and the total number of incorrect touches can bedisplayed on display panel 202 in real time. The time (spending and/orremaining) can also be displayed on display panel 202. In someembodiments, response times may also be recorded. The response time maybe measured from the time the visual indicator first appears on displaypanel 202 to the time when the sensor unit (either a correct or anincorrect one) senses the responding/reacting touch. Contact time mayalso be determined by, for example, method 500 illustrated in FIG. 5.

The sequence of visual indicators in react drills may be randomlygenerated. In some embodiments, controller 120 may be configured suchthat the same order of visual indicators in a random sequence is notrepeated.

Visual indicators may be displayed in different manners. For example,the visual indicator may display in a solid mode, in which the visualindicator is being displayed until the user touches a sensor unit. Inanother example, the visual indicator may display a flash mode, in whichthe visual indicator illuminates for a pre-determined duration (e.g.,0.10 to 10.0 seconds in increments of 0.10 seconds) and then disappears,regardless of whether the user touches a sensor unit during this timeduration. If the user fails to touch the corresponding sensor unitduring the pre-determined time duration, the failure to touch will betreated as an incorrect touch or an incomplete movement.

In some embodiments, the react drill may include a flip mode. In theflip mode, the user is instructed to react to the opposite sensorcorresponding to the displayed visual indicator. In one embodiment, theuser may be instructed to react to a diagonally opposite sensor. Forexample, if the top right visual indicator appears on the display panel,the user should react to the sensor unit on the bottom left. In anotherembodiment, the user may be instructed to react to a lateral oppositesensor. For example, if the top right visual indicator appears on thedisplay panel, the user should react to the top left sensor unit. In yetanother embodiment, the user may be instructed to react to a linearopposite sensor. For example, if the top right visual indicator appearson the display panel, the user should react to the bottom right sensorunit.

Sequence drills are similar to react drills. One of the differences isthat instead of random sequences, pre-determined sequences of visualindicators are used in sequence drills. The pre-determined sequences canbe generated by the software application or by the user. The user maysetup a sequence by inputting a series of numbers indicating thecorresponding sensor units. The total number of sensor units in asequence may vary. For example, in some embodiments, the total numbermay be from 1-20. In sequence drills, the number of correct andincorrect touches can also be provided and displayed on display panel202 in real time, similar to that of the react drills. The time(spending and/or remaining) can also be displayed on display panel 202.Contact time may also be determined by, for example, method 500illustrated in FIG. 5.

In both react and sequence drills, a time delay can be set between theappearance of a visual indicator and the receiving of a user response(e.g., a correct touch or an incorrect touch). For example, a 2-3seconds delay may be added before the user responds to the visualindicator.

After a user finishes a drill, controller 120 may save the result of thedrill. In some embodiments, controller 120 may provide comparative dataabout the current result and previous results of the user, therebyshowing whether the user's performance has been improved over time. Thecomparative data may be displayed on display panel 202 using a tabularview and/or a graphical view. The tabular view may include percentageimprovement or decrease, in addition to current result and past results.The graphical view may include bar/circle/curve graphicalrepresentations of the results comparisons.

Drills may be performed using either lower limbs (legs) or upper limbs(hands). In lower limb mode, sensor board 110 can be used to sense theuser's movements/touches. In upper limb mode, the user may perform thedrill by touching display panel 202 directly using his/her fingers.

Agility drills may be performed to test and/or improve the agility of auser. In an agility drill, the user responds to a sequence of arrowsdisplayed on display panel 202 and moves in the direction of the arrow.FIG. 6 shows an exemplary setup screen for performing an agility drillin an arrow sequence mode. In FIG. 6, eight arrows represent eightdirections identified by numbers 1 to 8. In the arrow sequence mode, theuser is able to program the sequence of the drill by inputting thesequence of numbers. Number 9 can be used as a wild card. Alternatively,in an arrow react mode, arrows may appear randomly.

The length of the agility drill can be programmed by time (e.g., 1second to 60 mins) or by arrow count (e.g., 1 to 20 arrows). The delaytime between the appearing of two adjacent arrows can also be programmed(e.g., from 1 to 20 seconds with incremental of 0.5 second).

Vertical drills may be performed to assess height of a user's jump. In avertical drill, the user stands on one or more of the sensor units,jumps, and lands on the same sensor unit. Controller 120 can detect theduration of time between the user's lift off from the sensor unit (e.g.,sensor unit released) and the user's next contact with the sensor unit(e.g., sensor unit compressed again). Contact time may also bedetermined by, for example, method 500 illustrated in FIG. 5. Bodyweight of the user can be taken into account to improve accuracy.Similar to those of count drills, the number of jumps and the time(spending and/or remaining) can be displayed on display panel 202 inreal time.

For every type of drills, the user can program the length of the drillby specify either the time duration of the drill or the target number oftouches. The target number of touches may include the number of correcttouches, the number of total touches (both correct and/or incorrect), orthe number of visual indicators appearing on the display panel.

Videos of a user performing a drill can be recorded. For example, avideo can be recorded using camera 216 (FIG. 2) that is equipped withcontroller 120. The recorded video may be provided to the user alongwith other performance data collected, for example, from sensor pad 110.

In some embodiments, sensor pad 110 may be replaced by a high speedcamera. For example, the high speed camera may be set up to synchronizewith controller 120 to monitor the user performing a drill. The user canplace any type of targets on the ground, e.g., a rubber mat, rubberdots, spray painted dots, etc., for the high speed camera to capture andregister the user's touch/contact actions or movements. In someembodiments, the camera can be used for gait testing and analysis,training and rehabilitation for high performance athletes, or generalrehabilitation patients.

In some embodiments, a user may create a use profile. The user profilemay include use data such as name, gender, age, height, weight, sports,position, injuries, etc. Performance data and videos of pre-set andcustomized drills may be saved based on user profiles. In someembodiments, performance data may be exported (e.g., as .csv files).

In some embodiments, an online database (e.g., database 172) may beprovided to users (e.g., for an annual fee or other suitable feestructures). The database may allow users to upload their saved drillresults for comparison with other users. Databases can be developed forthe general consumers, high school sports teams, collegiate sportsteams, professional teams, Olympic athletes, physical therapy clinics,sports medicine clinics, etc. Controller 120 may upload saved drillresults and the user profile data in order to compare the results. Auser profile may include fields for segregating, filtering, or targetingcertain user information, such as sports, position, professional level,demographic information to specific drills data and settings. Drillslisted in the online database may contain demo videos to display how thedrills should be performed.

Exemplary online databases include: (1) a performance database forindividuals, high schools and colleges to compare results to other usersaround the world; (2) a rehabilitation database for physical therapyclinics, collegiate/professional sports medicine staffs and sportsmedicine clinics; and (3) a high level athletic performance andrehabilitation database for professional sports teams or Olympic leveltraining facilities that includes normative data of athletes who possesssimilar performance abilities. The high level database may isolatenormative data from professional leagues, e.g., NBA, NFL, MLB, NHL, etc.
